HMC1044LP3ETR

Overview

The HMC1044LP3ETR is a programmable bandwidth low-pass filter (LPF) designed for wideband transceiver harmonic filtering applications. It features 16 user-programmable bands optimized for high and low cellular frequencies ranging from 1 GHz to 3 GHz. The device supports both single-ended and differential configurations, offering a passband insertion loss of 3 dB to 5 dB and a return loss greater than 10 dB. It operates on a DC supply voltage between 3 V and 3.5 V with a typical supply current of 1 µA. The component is housed in a compact 16-lead 3x3 mm QFN surface-mount package.

Feature Summary

• Programmable bandwidth selection across 16 distinct bands covering 1 GHz to 3 GHz
• Supports both single-ended and differential signal interfaces
• Designed to attenuate LO harmonics to improve modulator sideband and demodulator image rejection
• Low power consumption with minimal supply current requirement

Applications

• Filtering LO harmonics in quadrature modulators and demodulators
• Amplifier harmonic filtering in RF signal chains
• Wideband PLLs with integrated VCXOs
• Multi-standard, multi-carrier RF designs requiring field-configurable bandwidth

Procurement Notes

Verify the specific ordering suffix 'ETR' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the component status remains active or check for end-of-life notifications prior to finalizing procurement plans. Ensure compatibility with the specified 3x3 mm QFN footprint during PCB layout verification.

Selection Notes

Select this component when designing wideband transceivers requiring flexible harmonic suppression across cellular bands. Evaluate the need for 16 programmable bands versus fixed solutions based on system flexibility requirements. Consider the trade-off between the compact 3x3 mm footprint and the complexity of implementing external DC blocking capacitors for proper AC coupling operation.

Part Context

The HMC1044LP3E belongs to the HMC1044 family of programmable harmonic filters manufactured by Analog Devices Inc. This series targets applications utilizing quadrature modulation and demodulation where LO harmonic content can degrade performance. The ETR suffix denotes the specific tape and reel packaging variant of the base HMC1044LP3E model.
